Melua holds the record for playing the world's deepest underwater concert
Singer Katie Melua has played down a "small incident" that left her out of air while diving in a west London lake.
Melua, 25, was diving in a lake near Heathrow Airport when she accidentally - according to her website - "breathed in and choked on a lungful of water".
"The incident was all my own fault," she said of the mishap, first revealed by her musical collaborator Mike Batt.
Melua's spokeswoman said the Georgian-born, Belfast-raised singer had "had a fright" but was now "absolutely fine".
The singer, whose hits include The Closest Thing to Crazy and Nine Million Bicycles, is known for her love of extreme sports.
'Such an idiot'
The incident on Saturday came to light earlier this week when Batt revealed on micro-blogging site Twitter that Melua had had "an 'I'm about to die' moment".
Melua subsequently published a full explanation of what happened on Thursday, telling her fans via her website she had been "such an idiot".
"I really hope this hasn't put anyone off diving," she continued. "It's still one of my favourite things in the world to do."
Born in the former Soviet republic of Georgia, she become a British citizen in 2005.
The following year she performed the world's deepest underwater concert by singing for workers 303m below sea level on the Statoil Troll A gas rig in the North Sea.
